+## General information about tokens
+
+- https://github.com/yt-dlp/yt-dlp/wiki/PO-Token-Guide
+
+## YouTube Proof-of-Origin Token plugin
+
+To generate tokens TubeSync is using a plugin for `yt-dlp` from:
+* https://github.com/Brainicism/bgutil-ytdlp-pot-provider/tree/1.1.0/plugin/yt_dlp_plugins/extractor/
+
+#### Addition of plugin support
+
+Support for using the plugin was added in: https://github.com/meeb/tubesync/pull/1005
+
+#### Plugin web server URL
+
+This plugin communicates with a web service to retrieve tokens, for which it uses a default URL of: `http://127.0.0.1:4416`
+
+Because for TubeSync `openresty` or `nginx` are what most users will connect to with their web browser, the [configuration](../config/root/etc/nginx/token_server.conf) to listen on port `4416` has been added.
+
+If you are using another web server instead, you should configure similar proxying of the requests, or configure a different URL for the plugin to use.
+
+> [!TIP]
+> You can set the base URL that the plugin tries to access with a custom `local_settings.py` file.
+> 
+> ```python
+> YOUTUBE_DEFAULTS = {
+>     'extractor_args': {
+>         'youtubepot-bgutilhttp': {
+>             'baseurl': ['http://127.0.0.1:4416'],
+>         },
+>     },
+>     # ... all the other yt_dlp settings
+> }
+> ```
+
+#### Running the web service container the plugin communicates with
+
+Docker image: `brainicism/bgutil-ytdlp-pot-provider:1.1.0`
+
+```sh
+$ docker run -d \
+    --name bgutil-ytdlp-pot-service \
+    -p 4416:4416 \
+    --restart unless-stopped \
+    brainicism/bgutil-ytdlp-pot-provider:1.1.0
+```
+
+#### Configure the plugin using environment variables
+
+Because most users do not already have a custom `local_settings.py` file, and are not using a custom web server, an easier way to configure the plugin was developed.
+
+> [!NOTE]
+> You will need to add a new container so that your `TubeSync` container can access it.
+
+After that is running, you can set the new environment variables to use the web services provided by that container:
+
+```sh
+$ TUBESYNC_POT_PORT=4416
+$ export TUBESYNC_POT_PORT
+$ TUBESYNC_POT_IPADDR=[Whatever IP you are using]
+$ export TUBESYNC_POT_IPADDR
+```
+
+> [!IMPORTANT]
+> Don't forget to add `-e TUBESYNC_POT_IPADDR -e TUBESYNC_POT_PORT` to the `docker run` command that you are using with `TubeSync` as well.
+
+> [!TIP]
+> Setting `TUBESYNC_POT_HTTPS` to `True` will connect using `https://`[^1] instead of `http://`.
+
+[^1]: Setting up valid certificates for the web service is outside the scope of this guide.
+
+#### Using the `--link` flag with `docker run`
+
+When you have both containers on the same `docker` host, it can be very convenient to use this method.
+
+Environment variables are automatically created by `docker`, and support for using those was included.
+
+For a web service container named `bgutil-ytdlp-pot-service` you would add this `--link` option to your `docker run` command for TubeSync:
+
+```sh
+$ docker run --link 'bgutil-ytdlp-pot-service:POTServer' # everything else
+```
+
+#### Checking that things are working
+
+The web service provides a `/ping` endpoint.
+
+```sh
+$ no_proxy='127.0.0.1' curl 'http://127.0.0.1:4416/ping' ; echo
+{"token_ttl_hours":6,"server_uptime":1633.034876421,"version":"0.8.4"}
+```
+
+If the `curl` command above works from inside the TubeSync container, then the web server configuration is proxying the requests as expected.
+
+When it is not configured, the same `/ping` request receives a HTTP 502 error.
+
+#### More information about the web service the plugin uses

+Added environment variables:

+- TUBESYNC_POT_IPADDR
+- TUBESYNC_POT_PORT
+- TUBESYNC_POT_HTTPS (use https:// when set)
+- YT_POT_BGUTIL_BASE_URL (`youtubepot-bgutilhttp:base_url`) (not set by the user)
